UNITED STATES JOHN S. FISH, OECLEVELAND, OHIO.

IMPROVEMENT IN STREET-LAMPS.

Specification forming part of Letters Patent No. 127,685, dated June 11,1872.

SPECIFICATION.

1, JOHN S. FISH, of Gleveland, in the county of Ouyahoga and State ofOhio, have invented a new and Improved Street-Lamp, of which thefollowing is a specification:

This invention relates to a lamp constructed to be used out of doors andto burn the lighter products of petroleum, giving a brilliant cheaplight, and is described as follows:

In the drawing, Figure 1 is a side elevation, and Fig. 2 is a verticalsection, of the abovenamed lamp.

Arepresents a street-lamp frame constructed in the usual form, the topof which, however, is so constructed that it will prevent the wind fromblowing out the light. In the bottom of said frame is placed the fountof a lamp, made square and tapering so as to fit the frame. Said lampconsists of an outer case or jacket, B, 0 being the fount or body of thelamp for holding the oil or fluid. The space between the jacket and thefount is open at the bottom. The jacket B is designed to receive theheat from the sun and prevent the oil from becoming heated and wasted byevaporation. This precaution is necessary in the warm seasons of theyear, but is of no special use in cold weather. Within the fount 0stands a tube, D, having open spaces at the bottom, so that oil can passinside of it. Placed inside of the tube D is a tapering cup, E, having aflange at the top which rests on the tube. At the top of said cup is asmall annular chamber, 6, having several holes in the under side toadmit the gas or vapor which may arise from the oil in the fount. To oneside of the cup E is attached a thumb-rod, f, which passes through thesmall chamber a and a small tube, i, at tached to the top of the cup,and reaching up through the cover G of the jacket B. In the bottom ofthe wick-tube H, which is secured in the bottom of the cup E, aresituated the wick-wheels K K, the wheels being connected with the thumb-rod f by gear-wheels m n. The object of placing the wick-wheels in thelower end of the tube is that there may not be any openings in the topof said tube,

which would allow the escape of gas and endanger the safety of the lamp.The burner O is attached to a tube, P, having its lower portion, belowthe top of the cup E, perforated. The lower end of the tube P fitsclosely in the bottom of the cup E, but is not fastened, and passes upthrough the cover G of the jacket B. The top of the cup E around thetube P is open, through which air may enter,passin g in through theperforations for feeding the flame of the burner. This serves to keepthe oil cool in the fount and prevents its becoming heated by theburner. On the burner is placed a glass chimney, 0, in the ordinarymanner. In the tube P above the cover G is made an opening, 9, having asmall slide, 1', for covering the same. This opening is for the purposeof lighting and extinguishing the lamp. In the top of the frame A isplaced a tube, S, open at both ends, and having a second tube, T, whichtelescopes in it, and havin g a funnel-shaped mouth with a flangefitting in the top of the chimney. Over the top of the tube S is placeda cap, U, secured to the dome of the lamp-frame A. This prevents windfrom blowing down and extinguishing the light.

To remove the chimney the tube T may be pushed up so that the taperingportion will wedge in the tube S and remain; the chimney may then betaken out for cleaning or trimming of the wick.

Claim.

1. The combination of the wick-tube H, per

forth.
